1. Nitrogen(V) oxide decomposition reaction: N2O5=N2O4 1/2O2 is a first order reaction. The reaction rate constant at 328K is 1.5*10-2 s-1. The initial concentration of N2O5 is 0.93 mol/dm3. Determine: 1) N2O5 concentration 2 minutes after the start of the reaction; 2) the time during which the concentration of N2O5 will decrease by 3 times.
